1 . Until now, dressing robots, designed to help an elderly person or a person with a disability get dressed, have been created in the laboratory as a one-armed machine, but research has shown that this can be uncomfortable for the person in care.
To solve this problem, Dr Jihong Zhu, a robotics researcher at the University of York’s Institute, proposed a two-armed assistive dressing plan, which has been inspired by caregivers who have demonstrated that specific actions are required to reduce discomfort to the individual in their care.
Dr Zhu gathered important information on how care workers moved during a dressing exercise, through allowing a robot to observe and learn from human movements and then, through AI, generate a model that mimics (模仿) how human helpers do their task. This allowed the researchers to gather enough data to illustrate that two hands were needed for dressing and not one, as well as information on the angles that the arms make.
Dr Zhu said, “We know that practical tasks, such as getting dressed, can be done by a robot, freeing up a care worker to concentrate more on providing companionship and observing the general well-being of the individual in their care. It has been tested in the laboratory, but for this to work outside of the lab, we really need to understand how care workers do this task in real life.”
“We’ve adopted a method called learning from demonstration, which means that you don’t need an expert to programme a robot; a human just needs to demonstrate the motion that is required of the robot and the robot learns that action. It is clear that for care workers two arms are needed to properly attend to the needs of individuals,” Dr. Zhu said. “With the current one-armed machine scheme a patient is required to do too much work in order for a robot to assist them, moving their arm up in the air or bending it in ways that they might not be able to do.”

2 . Leading museums in the United States are covering up or closing displays featuring Native American cultural objects owing to new federal rules. The new regulations require museums to obtain “free, prior and informed permission” from tribal leaders before displaying ancestral heritage items.
The American Museum of Natural History in New York City, the largest natural history museum in the world, announced on Jan 26 that it would close two halls spanning 10,000 square feet with Native American exhibits, as the exhibits are “severely outdated”. “The halls we are closing contain artifacts (历史文物) of an era when museums such as ours did not respect the values, perspectives and indeed shared humanity of Native Americans,” museum President Sean Decatur said in a letter to the staff, The New York Times reported. “The number of cultural objects on display in these halls is significant, and because these exhibits are also severely outdated, we have decided that rather than just covering or removing specific items, we will close the halls,” Decatur said. The move comes because of the implementation (执行) in early January of update d regulations under the Native American Graves Protection and Repatriation Act (NAGPRA).
Over the next five years, museums, universities, art institutions and similar places are required to undertake essential updates to prepare all human remains and related funerary (葬礼的) objects for repatriation (遣送), making sure that tribes have more power and increased authority throughout the process. “The ultimate goal of the law is not to cover up exhibitions. It’s not to prevent appropriate education about diverse native cultures. It’s about repairing and repatriating items that have been stolen over the last couple of centuries and returning them to the rightful people,” Shannon O’Loughlin, the CEO of the Association on American Indian Affairs said.
Chicago’s Field Museum earlier this month also closed several displays featuring Native American cultural items. The Field Museum has one of the biggest collections of Native American remains in the country and opened a new permanent exhibition in the spring of 2022 that displaced the museum’s longstanding Native American exhibition since the 1950s.
Harvard University, which has more than 5,000 Native American human remains, has said it will remove all Native American funerary items from its exhibits. “Exhibitions have always been discussed during tribal discussions and cultural items have been removed from display at the tribal request. With the new NAGPRA regulations, the museum is in the process of removing all the funerary belongings and likely funerary belongings off display,” Harvard University’s Peabody Museum of Archaeology and Ethnology, said in a statement.

4 . In late September, an international team of researchers spread out across a remote New Mexico mountain range in search of a plant. The group walked through the rough landscape looking for signs of plants hugging a tree. Seven days later, the scientists left with a sample of nature’s reward: wild bean plants.
The scientists wanted to collect the legume (豆科植物), which is native to dry regions of the southwestern United States and northwestern Mexico. “The plants have adapted to this very hot and dry climate, so they have exception al drought and heat tolerance,” said Sarah Dohle, an expert with the U. S. Department of Agriculture.
A warming planet is causing huge damage to agriculture around the globe. In the western U. S., a severe drought affected California’s tomato and rice production. In Guatemala, the combined effects of both drought and rain decreased corn and black bean harvests. In Sub-Saharan Africa, hot conditions have reduced the yields of wheat and corn by more than a third since the early 1960s.
“Crops like the wild bean could help diversify food production, and their genetic material may help make other crops more drought- and heat-tolerant,” said Richard Pratt, who is among a growing number of scientists working to look for crops adapting to climate change.
The University of California is leading a multi-state $15million project involving 20 institutions to speed up the breeding (繁殖) cycles of wheat and to research ways to help the crop grow in a toughened environment. At Auburn University in Alabama, scientists are working to breed a peanut variety that can better tolerate drought conditions. And scientists from various institutions have taken part in an effort funded by the Norwegian government to identify, collect and evaluate wild crops for future development.
Still, there are numerous challenges at play: Crop breeding is a time-intensive process, so it can be difficult for scientists to keep pace with rapidly changing weather. Advances in gene editing can help speed up the process, but come with their own trials.
“As global climate change keeps being hard on us,” Sarah said, “there isn’t plenty of time left for us to get crops that are adaptable.”

5 . A study, published in European Heart Journal, is the first to assess how different movement patterns throughout the 24-hour day are linked to heart health.
In this study, British researchers analyzed data from six studies, involving 15,246 people from five countries, to see how movement behavior across the day is associated with heart health. Each participant used a wearable device, a key novelty, on their thighs (大腿) to measure their activities throughout the 24-hour day and had their heart health measured.
The researchers identified a series of behaviors that make up a typical 24-hour day, with time spent doing moderate-vigorous activity providing the most benefit to heart health, followed by light activity, standing and sleeping compared with the negative impact of sedentary (久坐) behavior. The team modeled what would happen if an individual changed various amounts of one behavior for another each day for a week, in order to estimate the effect on heart health for each scenario. When replacing sedentary behavior, as little as five minutes of moderate-vigorous activity had a noticeable effect on heart health.
Dr. Jo Blodgett, first author of the study, said, “The big takeaway from our research is that while small changes to how you move can have a positive effect on heart health, intensity of movement matters. The most beneficial change we observed was to replace sitting with moderate-vigorous activity, which could be a run, a brisk walk, or stair climbing, basically any activity that raises your heart rate and makes you breathe faster, even for a minute or two. ”
Dr. Jo Blodgett also pointed out that although time spent doing vigorous activity was the quickest way to improve heart health, there are ways to benefit for people of all abilities — it’s just that the lower the intensity of the activity, the longer the time is required to start having a reliable benefit. Using a standing desk for a few hours a day instead of a sitting desk, for example, is not only a change over a relatively large amount of time but is also one that could be combined into a working routine fairly easily as it does not require any time commitment.

9 . Where do you expect to see graffiti (涂鸦)? Probably not in a museum. Bristol Museum and Art Gallery, in the south-west of England, was the kind of place you went to see classical statues and stuffed animals in cases until the arrivals of the ‘Banksy Versus the Bristol Museum’ exhibition in 2009. The exhibition hosted more than 100 works by Banksy, one of the world’s most famous graffiti artists.
Banksy is a man of mystery (神秘). He hardly ever gives interviews and likes to be anonymous (匿名的). Nobody knows much about his life or his background but many people believe that his real name is either Robin Cunningham, Robert Banks or Robin Banks and that he was born in 1973 near Bristol.
Banksy’s questioned ‘street art’ includes paintings on live sheep and cows and graffiti on the huge wall put up to divide two areas. Brand Pitt spent over 82 million on a Bansky original. Banksy designed an album cover for the Britpop group Blur in 2003 but he has refused requests to do adverts for Nike. A year after the Bristol exhibition, Banksy made a film called Exit Through the Gift Shop. The film tells the story of a French street artist in America. Exit Through the Gift Shop received many positive reviews. Nobody knows if it was about a real artist or an invented character from Banksy’s imagination.
Bristol isn’t the only place in Britain to welcome graffiti. The DPM Park in Dundee, Scotland has the longest legal graffiti wall (almost 110m long) in the UK. Anyone can paint on the council-owned wall any time they like. Mike Crilley, the graffiti wall project organiser, promotes the positive side of graffiti and runs workshops for local children.
Is everyone doing graffiti? Can we do graffiti where we want these days? Not exactly. It’s illegal to paint on somebody else’s possessions, so make sure you find a legal graffiti wall like the one in Dundee if you want to have a go.
